$PECEFICATION forming part of Letters Patent No. 334,614, dated January 19, 1886.

Application filed June 26, 1885. Serial No. 169,868. (No model.)

To all whom it may concern.-

Be it known that I, WENrwoRTH G. RICK- ER, of Rochester, New York, have invented certain Improvements in Hay Carriers, of which the following is a specification, reference being had to the accompanying drawings.

My present invention relates to certain improvements on the hay-carrier patented to me September 11,1883, No. 284,903, which improvements consist, principally, in attaching the binding pulley to a swinging frame pivoted to the frame of the machine in such relation to the carrier-sheave as to bind or clamp the draft-rope more firmly between the pulleys and sheave when the draft is released,and in certain other changes and additions by which the apparatus is arranged to work more effectively, all as hereinafter more fully described and claimed.

My improvements in hay-carriers are representedin the accompanying-drawings,in which Figurel is a side elevation. Fig. 2 represents the sliding trip-frame detached. Fig.3 represents the trip-bar, as seen from above. Fig. 4 is a central longitudinal section showing the parts beyond the plane of sect-ion. Fig. 5 represents one of the sliding dogs. Fig. 6 is another view of the same. Fig. 7 is aside view of the sliding cam and one of the dogs. Fig. 8 is a central longitudinal sectionthrough the sliding cam and binding-pulley on line 2 2, Fig. 10. Fig. 9 is a section on the line w 00, Fig. 1. Fig. 10 is a plan view of the sliding cam. Fig. 11 is an end view of the same, as seen from the right hand in Fig. 10. Fig. 12 is a side elevation of the binding pulley and frame detached. Fig. 13 is an elevation of the same, as seen from the right hand in Fig. 12. Fig. 14 is a side elevation of the main carriersheave, binding pulley and frame, sliding cam, and dogs. Fig. 15 is a side elevation of the binding pulley and frame, and the sliding cam, in different positions from that shown in Fig. 14. Fig. 16 is a plan View, the track-beam being removed. Fig. 17 is an elevation of one of the side frames, as seen from the inside. Fig. 18 is a section of aportion of the frame on the line y y, Fig. 17. Fig. 19 is an end view of the stop-block. Fig. 20 is a side View of the same.

In the accompanying drawings, A is the track-beam, which supports the frame-work B B of my improved hay-carrier, by means of the flanged wheels 0 C, which turn on studs attached to the upper part of the frame. The two frames B B inclose the track-beam and the operative parts of the apparatus between them, being connected. together by bolts or rods 0 c, d, and a. The wheels 0 C are arranged in two sets applied to the inside of those portions of the framework which extend above the track-beam, an interval or space being left between the inner faces of the wheels, to permit the passage of the catch-pin G and lever H, if the latter be used, between the wheels when the carrier travels along the trackloeam.

D is the draft-rope, one end of which is attached to the binding-pulley F by means of the clevis g and hook K, while the other end, after passing through the pulley block or blocks J J, to which any ordinary slings or hay-fork may be attached, is carried over the sheave E and under the binding-pulley F, and

' led off through suitable corner-pulleys, if ne cessary, and connected to the source of power by which the machine is operated.

M is the return-rope, which is simply for drawing the carrier backward after the delivery of the load from the slings or fork, and may be led through any suitable corner-pulleys. It is-inserted and fastened in a staple or hole, k, in one of the side frames, B B. The slings are attached to the hooks on the pulleyblocks J J, and their construction and mode of operation are too well known to require further description here.

When my improved hay-carrier is used with a fork, only a single pulley block J will be annexed, the carrier is represented as arranged to travel toward the right hand, the strain of the draft-rope being resisted by the stop-block m, bearing against the lower end of the sliding catch-pin G. \Vhen the load has been ele' vated, the pulley block or blocks J J strike against the plate N at the lower end of the trip-frame and cause it to move upward, as indicated by the dotted lines in Fig. 1, and the trip-bar O raises the catch-pin G so as to release it from the stopblock m, and thus allows the carrier to travel along the trackbeam toward the right hand. My improved hay-carrier may, however, be arranged to travel in the opposite direction without making any alterations in it, by simply placing it on the track-beam in a position the reverse of that shown in Fig. 1.

Referringnow moreparticularly to thedctails ofthe construction ot'my improved hay-carrier, it will be observed that the main carryingsheave E is arranged to rotate freely on a bolt or stud, d, secured to the side frames,B B, and that it has a peripheral groove in which the draft-rope 1) runs, the edges or flanges of the sheave being provided with the projecting lugsff, with which the sliding dogs 0 0' engage to prevent the turning of the sheave from right to left in Fig. 1, when the load is being elevated or conveyed along the track. As will be seen from an examination of Fig. 5, the lower ends of the dogs are rounded or beveled, and a corresponding bevel or inclination is given to the sides of the lugsff, so that as the sheave revolves the dogs will be moved upward by the lugs, falling again by gravity, so as to interpose their points in the path of the revolution of the lugs. The lugs are so arranged on the edges of the sheavethat while one of the dogs is rising the other is falling. The lugs on one side of the sheave are placed opposite the space which intervenes between the lugs on the other side. In this way the sheave E is prevented from turning backward, or from right to left in Fig. l. The binding-pulley F is provided with a peripheral groove for the draftrope, and is arranged to revolve freelyon the stud c, which passes through the clevis g and the biuding'frame L and connects these parts together. The binding-frame L is pivoted on the bolt 12 passing through the side frames, B B, and sustains the binding-pulley in position, so that it may -swing up and down between the frames to and from the carryingsheave E, as indicated by the full and dotted lines in the figures. The olevis is provided at its lower end with the hook K or other means for the attachment of the end of the rope D thereto, so that a portion of the weight of the load is carried by the binding-pulley. The binding-pulley is narrower than the carrying-sheave E, so that its edges may enter between the flanges on the latter, and the rope be clamped or bound between them when the binding-pulley is in the lowest position. The sliding dogs 0 oare arranged to move up and down in suitable grooves in the side frames, and. are provided at their upper ends with the projecting pins 1) 1), which extend over the beveled arms 8 s of the sliding cam P, which is constructed to travel along in suitable ways or guides in the side frames, for the purpose of raising the dogs 0 0 or allowing them to fall, being moved in one direction, from right to left in Fig. 14, by the friction of the revolving binding-pulley, and in the other by contact with the lower end of the catch-pin G.

The shape of the sliding cam will be understood from an examination of Figs. 8, 10, 11, and 14.. It consists, essentially, of a transverse body, a, Fig. 10, the two parallel arms 3 s, the upper surfaces of'whieh are beveled or inclined to operate the sliding dogs 0 0, the lug or projection 1, which strikes against the catch-pin G, the downward projection 1), Figs. 4, 8, and 11, which acts as a frictionsurface to receive motion from the revolving binding-pulley F, and the arms a a, which at certain times engage with the lugs (Z d on the binding-frame L, as represented in Fig. 14. The sliding cam is arranged to slide backward and forward in suitable ways or guides, c, Fig. 17, in the side frames. The lug r projects inward from the body of the sliding cam, its end being adapted to strike against the catch-pin, and to thereby force the sliding cum from left to right in Fig. 1, when the carrier returns to receive a fresh load. The arms a a extend downward and outward on each side of the body a, in such position that the arms h h of the binding-frame can pass in between them, and allow the projecting lugs d d to rest on the upper surfaces of the arms a a in a certain position of the parts. The lug I) extends downward from the body a, its lower surface being rounded and adapted to come in contact with the curved surface of the groove in the binding-pulley F, so that the cam may receive motion therefrom. (See Figs. Sand 11.) The arm t reaches outward from the body of the sliding cam, between the arms a it, its upper surface being preferably recessed, as shown in Figs. 10 and 16, to save weight, and its lower surface being curved or rounded and adapted to the shape of the groove in the bindingpulley F, so that when the pulley is elevated, as indicated by the dotted circles in Figs. 4 and '7, it may act as a stop to prevent the accidental movement of the sliding cam, which would throw the dogs 0 0 out of engagement with the lugsff on the main carrying-sheave E. The dogs 0 0 are arranged to slide up and down, to and from the main carrying-sheave, in suitable guides or ways, It, Figs. 17 and 18, in the side frames. The lugsj, Fig. 1, projecting outward on each side from the frame, serve as guides forthe rods qq of the tri p-frame. The trip-bar O is preferably provided with an inclined surface, 0, which preventsit from jamming against the lower end of the catch-pin G. The stop-block m is beveled on its uppersurface toward the outside, so that when the carrier returns the catch-pin G will be forced to rise IIS up over it. The stop-block mmay be held in place by the bolt 0 passing through it; but I prefer to construct it as shown in Figs. 4, 19. and 20, with a notched flange, q, and projecting lugs r T, which project into recesses 22, Fig. 17, in the side frames. This construction facilitates the removal of the stop-block, when desired.

, As indicated at t, Figs. 4 and 17, the side frames are flanged or bent inward to hold the rope D on the carrying-sheave E.

It is obvious that thebinding-pulley F may be made to slide up and down in grooves or guides in the side frames, the binding-frame being dispensed with; but I prefer to employ the latter, as I thereby secure greater freedom of action among other advantages.

The operation of my improved hay-carrier is as follows: Supposing the hooks on the pulley-blocks J J to be engaged with the slings which underlie the load which it is desired to elevate and transfer to a different location, the parts of the apparatus will occupy the positions shown by the full lines in Fig. 14, and any strain applied to the draft-rope D will straighten the rope and raise up the bindingpulley F and frame L, lifting the lugs d d from the arms a a and bringing the surface of the groove in the binding-pulley against the lower side of the lug b on the sliding cam P, (see Fig. 11,) so that the latter is moved by the friction of the revolving binding-pulley toward the left hand in Fig. 14, thereby allowingthe dogs 0 0 to fall, so that their points can engage with the lugs ff on the main carrying-sheave E. The load is now lifted by the continued movement of the rope D, the sheave E revolving and the lugs ff on it causingthe sliding dogs to rise and fall as they pass under the lower ends. The binding-pulley F also revolves as the rope travels along beneath it, and the sliding cam P is prevented from accidentally sliding back to its original position by the binding-pulley COlI1 ing in contact with the curved lower surface of the projecting arm t. The load continues to rise until one of the pulley-blocks J J comes in contact with the plate N at the lower end of the trip-frame, and raises it up, as indicated by the dotted lines in Fig. 1, which movement is transmitted by the rods q q to the trip-bar O, which rises and forces the catchpin G upward until the stop-block m can pass underneath it, thereby releasing the carrier, so that it may travel along toward the right hand in Fig. 1. When the load has arrived over the point where it is desired to deposit it, it is released from the sling or the fork by any ordinary device in use for this purpose, operated by a cord, if necessary. The car is now returned to its first position by means of the return-cord M, and, at the end of its return movement the lug r on the sliding cam P strikes against the lower end of the catch-pin G, and the cam is thereby caused to slide toward the right, thus leaving the parts in the position shown in Fig. 14, ready fora repetition of the operation. When'the carrier returns, the catch-pin G is caused to slide upward by the inclined surface of the stop-block m. (See Fig. 4.) My improved hay-carrier is so constructed that it will sustain the load at any point in its elevation. Thus in case of an intentional or accidental release of the strain on the draft-rope, the bi nding-pulley F will settle down to the position shown by the full lines in Fig. 1.. thereby bindingfthe rope firmly against the surface of the carrying-sheave E and preventing the rope from slipping along around the said sheave. The sheave is prevented from turn ing backward by the dogs 0 0 engaging with the lugs ff on its edges; but the draft-rope might, under heavy strain, slip around it, were itnot bound by the pressure against it of the pulley F, produced by that portion of the weight of the load which is sustained by the binding-pulley.

If it is desired to stop the elevation of the load at any point short of that at which the pulley-block comes in contact with the tripframe, the catch-pin G may be raised,so as to allow the carrier to travel along the trackbeam, by means of the cord a and lever H, Fig. 1. The cord (it passes over a suitable pulley, and thence downwardwithin reach ofthe operator. By pulling on the cord the lever H and catch-pin G are raised, as shown by the dotted lines in Fig. 1, so that the carrier can move along the track-beam and transfer the load to the desired place of deposit. The end of the lever His guided inasuitable slotted standard. I, attached to the track-beam. The upper end of the catch-pin is arranged to slide through the lever, so as to be capable of independent action when necessary. A pin, b, or nut on the upper end of the catch-pin causes the latter to move upward when the lever is raised.

A rope is attached to the sling or fork, so that it can be drawn down at the end of the return movement of the carrier. In order to prevent the binding-pulley at this time from binding on the draft-rope, so as to prevent its passing backward around the sheave E, I apply to the bent arm h h of the binding-frame L the projecting lugs d d", which engage with and bear on the upper edges of the arms a a of the slidingcam P, so as to sustain the binding-pulley in an elevated position, as represented in Fig. 14, and to prevent the draftrope from being clamped between the binding pulley and the sheave E. In case at the end of the return movement of the carrier the binding pulley and frame are in one of their lower positions, as indicated in the full lines in Fig. 1, the ends of the arms a u on the sliding cam, when the latterds forced back by contact with the catch-pin G, press against the lugs d d on the binding-frame (see Fig. 15) and cause the latter to swing upward until the arms can pass under them, thereby elevating the bindingpnlley and keeping it in an elevated position until the draft-rope is again straightened by the strain caused by elevating the load.

In a modified form of construction I have arranged the sliding cam P to be operated by the return-rope M, or by a separate rope, instead of by the friction of the binding-pulley against the lower surface of the lug b,- but I prefer to employ the automatic arrangement herein described.

In another modification of my improved haycarrier I have provided the bindin ulley with lugs, Ii'kef, on the main carrying-sheave, or with ratchettccth, and have arranged a series of sliding dogs or pawls on the bindingframe L, to engage with the lugs or teeth to prevent the reverse rotation of the bindingpulley, the said lugs or teeth being operated by the sliding cam, so as to be thrown out of action when the cam is forced to the right in Fig. 1. This arrangement may be employed either with or without means for arresting the reverse movement of the main carryingsheave E.

I do not claim herein anything which has been shown and described in my previous patent.

The combinatiomwith thetraveling frame BB, of the carriersheave E, swinging bindingpulley F, attached to the end of the swinging binding-frame L, pivoted to the frame of the machine, so that the binding-pulley can swing between the frames 13 B. and the draft-rope I), attached at one end to the binding-frame, substantially as described.
